Dry ice is readily manufactured as : Carbon dioxide-rich gas is pressurized and refrigerated until it changes into its liquid form. The pressure is reduced. When this occurs some liquid carbon dioxide vaporizes, and this causes a rapid lowering of temperature of the remaining liquid carbon dioxide. The extreme cold makes the liquid solidify into a snow-like consistency. The snow-like solid carbon dioxide is compressed into either small shots or larger blocks of dry ice.
